Application led, ctober 12, 1929; Seria11No.399,238. ,4 y l My present invention relates to the jewelry art, and has'partoular reference to eXtenSlble bracelets, watch straps, and the' like.

-v(,)neobjeet of the Vinvention is to provide a i, novelwdlllstingmechanism for Jewelry of this oharaoten f `Another ob'oot is to Provide a Strpfol'med of two `separate parts which maybe secured wgethi' in'djllsted relative position. Y

which grips the edges of an associated strap. lWith these and other objects Aand advantageous features in view, the invention consists of the.v novel arrangement of parts more d description following, in ,conjunction with the accompanying drawings, and more particularly set forth `in the appended claims. In thedrawings:

, Fig. 9 is a section on the line 9-9 of Figf It has been found desirable in the `jewelry art to provide 1an extensiblebraceletor the like with adjustable locking kvmechanism, which will vnot `bec-onspicuous and which will sei tion until manually released. I have devised nextensible bracelet formed of two portions which are relatively'movablm'with a locking mechanism which includes a clamp'member provide a novel locky curely holdthebracelet in the desired. posin i the @dei one Portion which is engaseble .with the other portion, and a loch member on the end of the other portion whichv grips the edges tions together, and which is manuallyreleasable when itis desired tochange the length of the bracelet; and the followingis a detailed description of a speciiic embodiment of my invention showing the novel locking mecha-l nism appliedto a bracelet formed of separate metal links. l A f l l, e

Referring to the drawings, l() designates a bracelet, which is formed of two [separate parts 11, 12, which may be termed the upper and the lowerportion, and which `are secured together by locking zmechanismy comprising a clamp member 13 and a locky member-14'. The clamp member 13 is secured to the end of the lower strap portion 12,.andrinclude's a saddle 15 normally mounted to slide over the upper strap portionfllv and a bent -lever f clamp 16 which has extensions 1-7 pivotally mounted in suitable openings 18 :of the saddle` 15, anV eye 19-being provided on the clampv 16 for securing the end ofthe lower strap portion 12 thereto. As .shown by Figure 3, a movement of the vlower strap portion end away from the upper strapportion willl turn the clamp 16 and release the upperk strap portion 11, while a movement of the end of strap portion 12`toward the strap portion l1A will turn the clamp 16 portionbetween the clamp 16 and the saddle 15.

The lock member 14 is secured to the upper strap portion 11 through the usual eye 20. an

includes afcasingV 21, whichl is vpreferably A formedv from sheet metal with two end walls 22, 23, the end wall 22 terminating in the norr -mally downwardly extending bentinger having an upward lateral .lock tooth 25. The side wall 23 has a slot 26 therein through which a T-shaped bar 27 extends, as shown in 'Figure 9, the undersides 28 of theT head 29 being engaged by a compression spring 30 to yieldingly force the into the housing 21. rIrfhe of the first portion tov lockthe .twopforg` y to clamp the upper strap,y

The operation ofthe improved lockingv mechanism is as follows:

sion of Vspring V releases the lock tooth 32 from locking engagement with theslot in the lowerk portion 12 and lpermits relative movement of the two strapportions withfrespect to each other. A movement of the end of portion 12-away from portionll now moves Y .the clamp 16 and releases the clamp member from clamping engagement with the upper portion 11,-thus permitting adjustment ofthe braceletito the desired length. c To adjustably lock the two portions together, the. clamp member 13 is clamped to. the upperportion 11 andthe lock member 14is moved over thelovv er portion 12 until the two strap portions con ftact. with each other and the lock tooth A26 enters an opening 34. The other. finger 31 is ,now permitted 'to kmove inwardly under the pressure of thefspring, the lock tooth 32 entering an opening 35 aligned with the opening-34 receiving the lock tooth 26, thetension of the spring 30 now holding the two fingers 24 vand 31 andthe V.lock teeth 25 and 32 in Vlocked position. i

My improvedlocking. mechanism is not conspicuous, is instantly adjustable to provide a' desired length of the extensible bracelet, strap or the like, and securely clamps the two bracelet portions at one point and locks the two portions at another point.

While I have described one specific embodiment as illustrating theprinciples of my invention, changes both in structure and arrangementmay obviously be made without departing from the spirit of the invention '50 as defined in the appended claims.
